Interface TemplateEngine

All Known Implementing Classes:

DefinedAttributeTemplateEngine

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface TemplateEngine

Renders an SQL statement from a template. Note for implementors: define a suitable public constructor for SqlObject's UseTemplateEngine annotation, and/or create your own custom annotation in case your TemplateEngine has configuration parameters! Suitable constructors are the no-arg constructor, one that takes a Class, and one that takes both a Class and a Method.
